Ukuba izixhobo zokukhusela azinkulu kangako okanye azilungelelaniswanga ngokwaneleyo, umngcipheko wokushisa kakhulu, ukukhubeka, kunye nomonakalo wezixhobo uyanda. Ukujongana nokukhula komthwalo kwasekuqaleni kwinqanaba loyilo kubalulekile ukuze inkqubo ithembeke ixesha elide.

2. Kutheni ukhuseleko lwangoku oluphakathi ukuya phezulu lufuna indlela eyahlukileyo yoyilo

Amanqanaba aphezulu ombane azisa imingeni eyahlukileyo enxulumene nokusebenza kobushushu, amandla okumelana nombane omfutshane, kunye nokuphazamiseka kwempazamo. Ngokungafaniyo nezicelo zombane ophantsi, ukhuseleko kolu luhlu kufuneka lulinganisele uvakalelo kunye nokuqina.
A 1200A MCCBidla ngokukhethwa apho iinkqubo zifuna uyilo oluncinci kunye nokusebenza okuthembekileyo kokuphazamiseka, okwenza ukuba ifaneleke kwiiphaneli zokusasaza eziphakathi ukuya kwezinkulu ekufuneka zisebenze ngokuqhubekayo phantsi kwemithwalo ephakamileyo.

3. Ulungelelwaniso oluKhethayo kunye nokuzinza kwenkqubo ekwandiseni iiNethiwekhi zamandla

Njengoko iinkqubo zamandla zisiba nzima ngakumbi, ulungelelwaniso olukhethiweyo luba lubalulekileyo. Ulungelelwaniso olufanelekileyo luqinisekisa ukuba sisixhobo sokukhusela esikufutshane nesiphako kuphela esisebenzayo, nto leyo enciphisa ukuphazamiseka kwenkonzo.
Ukhuseleko olulungelelanisiweyo luphucula ukusebenza kwenkqubo, luphucula ukhuseleko, kwaye luthintela ukucima kombane okunokuchaphazela zonke izakhiwo. Ukukhethwa ngobuchule kunye nokuseta izixhobo zokukhusela kudlala indima ephambili ekugcineni indlela yokuziphatha kwenkqubo ezinzileyo neqikelelweyo.

4. Ufakelo, Ukulungiswa Kwesithuba, kunye Nezinto Eziqwalaselwayo Ngokudityaniswa Kweephaneli

Amagumbi ombane anamhlanje adla ngokujongana nemida yendawo. Uyilo olufanelekileyo lwepaneli, umoya ofanelekileyo, kunye nokuhambelana neenkqubo zebhasi kufuneka kuqwalaselwe ngexesha lokufakwa.
Ii-current breakers eziphakathi ukuya kweziphezulu kufuneka zidityaniswe ngendlela exhasa ukuchithwa kobushushu kunye nokulungiswa okulula ngelixa zivumela indawo yokwandiswa okanye ukuphuculwa kwexesha elizayo.

5. Iziseko zoMbane eziQinisekisa iXesha elizayo ukuze zikwazi ukwandiswa kunye nokuthobela imithetho

Uyilo lokwandisa ubungakanani bezixhobo luqinisekisa ukuba izakhiwo zinokuziqhelanisa nokwanda kwamandla azo kwixesha elizayo ngaphandle kokulungiswa okukhulu. Ukuthobela imigangatho yamazwe ngamazwe efana ne-IEC kunye ne-UL kukwaqinisekisa ukhuseleko kunye nokwamkelwa kwihlabathi liphela.
Ngokubandakanya1200A MCCBkwiindlela zoyilo ezijonge phambili, iinjineli zinokwenza iinkqubo zombane ezixhasa ukukhula, ezihlangabezana neemfuno zomthetho, kunye nokunciphisa iindleko zokusebenza zexesha elide.

Isiphelo

Ukunyuka kwemfuno yamandla kufuna okungaphezulu kokuphuculwa okuncinci—kufuna ucwangciso olucwangcisiweyo. Ukukhetha isisombululo sokhuseleko esichanekileyo kwenza amaziko asebenze ngokukhuselekileyo, ngokufanelekileyo, nangokuthembekileyo njengoko imithwalo isanda. Xa isetyenziswa ngokufanelekileyo,1200A MCCBiba yinto ebalulekileyo ekwakheni iziseko zombane ezizinzileyo ezilungele imingeni yexesha elizayo.
